Abstract: Natural rubber has many uses in a variety of industries, enabled by ‘crosslinking’ between its tangled polymers, which creates elasticity. But rubber can crack and suffer fatigue. It is now shown that reducing the crosslink density in highly entangled natural rubber increases its crack resistance and prolongs its useful life.
